Hubble Detects Plasma Ejections Shooting from a Star

Hubble observations have revealed a string of super-hot blobs, each with a temperature of more than 17,000 degrees Fahrenheit, being ejected from a dying star. Great balls of fire! NASA’s Hubble Space Telescope has detected superhot blobs of gas, each twice as massive as the planet Mars, being ejected near a dying star. The plasma […]

Astronomers Discover Density Waves in a Protoplanetary Disk

Astronomers have discovered a striking spiral-arm structure in the disc of gas and dust around the young star Elias 2-27. The structure is made up of the matter near the midplane of the disc – the region in which new planets can be born. This means: the spirals are either a result of the presence […]

VISTA Views Messier 78

ESO’s VISTA reveals stars that are just forming within the cosmic dust of Messier 78. In this new image of the nebula Messier 78, young stars cast a bluish pall over their surroundings, while red fledgling stars peer out from their cocoons of cosmic dust. To our eyes, most of these stars would be hidden […]

New Study Predicts Next Global Dust Storm on Mars

Based on a historical pattern, scientists believe they can predict the occurrence of dust storms on Mars. Global dust storms on Mars could soon become more predictable — which would be a boon for future astronauts there — if the next one follows a pattern suggested by those in the past. A published prediction, based […]

Telescopes Reveal Evidence for Wandering Black Hole

Astronomers have discovered a “wandering” black hole in the outer regions of a galaxy about 4.5 billion light years from Earth. Evidence suggests this newly discovered black hole has about 100,000 times the Sun’s mass, and was originally located in a smaller galaxy that merged with a larger one. Astronomers have used NASA’s Chandra X-ray […]

Astronomers Study of Four Elusive Binary Systems

Astronomers from the Harvard-Smithsonian Center for Astrophysics have measured the orbital parameters of four millisecond pulsars in the globular cluster 47 Tuc and modeled their possible formation and evolution paths. When a star with a mass of roughly ten solar masses finishes its life, it explodes as a supernova, leaving behind a neutron star as […]

ALMA Views a Protoplanetary Disc Surrounding the Young Star Elias 2-27

This newly released image shows a protoplanetary disc surrounding the young star Elias 2-27. This beautiful image, captured with the Atacama Large Millimeter/submillimeter Array (ALMA) features a protoplanetary disc surrounding the young star Elias 2-27, some 450 light years away. ALMA has discovered and observed plenty of protoplanetary discs, but this disc is special as […]

New Hubble Image of the Center of NGC 247

This newly released Hubble image shows spiral galaxy NGC 247. NGC 247 is a relatively small spiral galaxy in the southern constellation of Cetus (The Whale). Lying at a distance of around 11 million light-years from us, it forms part of the Sculptor Group, a loose collection of galaxies that also contains the more famous […]

Final Descent Images from Rosetta Spacecraft

These newly released images are the last taken by ESA’s Rosetta Spacecraft shortly before its controlled impact into the comet 67P/Churyumov-Gerasimenko. A new image of comet 67P/Churyumov-Gerasimenko was taken by the European Space Agency’s (ESA) Rosetta spacecraft shortly before its controlled impact into the comet’s surface on September 30th, 2016. Confirmation of the end of […]

ALMA Views Massive Star ST11

Using the Atacama Large Millimeter/submillimeter Array, a team of astronomers reveal the first hot core to be found outside the Milky Way. A hot and dense mass of complex molecules, cocooning a newborn star, has been discovered by a Japanese team of astronomers using ALMA. This unique hot molecular core is the first of its […]

Possible Water Plumes Erupting on Jupiter's Moon Europa

Using the Hubble Space Telescope, astronomers have imaged what may be water vapor plumes erupting off the surface of Jupiter’s moon Europa. This finding bolsters other Hubble observations suggesting the icy moon erupts with high altitude water vapor plumes. The observation increases the possibility that missions to Europa may be able to sample Europa’s ocean […]

Astronomers Reveal Mercury is Active

New research suggests that Mercury is contracting even today, joining Earth as a tectonically active planet. Images obtained by NASA’s MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft reveal previously undetected small fault scarps— cliff-like landforms that resemble stair steps. These scarps are small enough that scientists believe they must be geologically young, which […]

NASA-Funded Sounding Rocket Solves One Cosmic Mystery, Reveals Another

New research confirms some of our ideas about where cosmic X-rays come from and reveals an entire group of X-rays that don’t come from any known source. In the last century, humans realized that space is filled with types of light we can’t see – from infrared signals released by hot stars and galaxies, to […]
